Hmm, happened to me also, but looks like mine was different. Turned out mine was calcium deficiency due to pH lockout.

it pretty much ruined my plant before i realized what it was.

 

[Jren437]

Do I flush?

Have you been checking the PH, thats usually why you get lock out. Adjust the PH if it isnt in range.

I always PH balance.... I let it range from 5.5 to 6.5 but always in that area

What strain is it? What EC/PPM levels?

 

[707humboldt]

If ph is in range it could be over feeding. How often are you feeding and at what ec/ppm?

Canna-tsu and I'm not sure about ex/ppms I feed 1/4 tsp per gallon dyna gro bloom and 1 tsp cal mag every other watering

i checked this and it looked a little like cal def, but I use cal mag regularly... But I did follow the flushing instructions they gave.... Hopefully that'll do it

less is more inmost cases

I've been running at 1/2 the recommended amount on nutes but I should run my ph 5.5-6.5 like hydro and not high like soil right?

 

[ugorg]

in soil i go for 6.5 this gives you better nute range and uptake in hydro such as nft systems aim for a ph around 5.8
